Do you have brain fog (e.g. impaired concentration, cognition, etc.)?
1) Always, almost always
2) Only during PEM, otherwise I am normal
3) Never, almost never (e.g. can read long complex books with no issues)
Would you consider adding something like,
Not all the time, but I have cognitive fatiguability, and constant brain fog during PEM/crashes.
I’m intrigued by MECFS patients with no brain fog....seems like they have a better prognosis. I think under IOM you can be diagnosed without cognitive issues.
I am one of these. At least, when my ME was mild, I managed to keep working part time as a Maths teacher as well as doing an Open University Maths degree very part time. I only had brain fog when in PEM/ crashed then.
My main problem was physical fatiguability and pain, and PEM when I overdid it physically (as little as walking 100 metres several times in a day). Plus a range of the usual extras like OI, nausea, headaches, sore throats, etc etc.
Now my ME is physically pretty severe but my brain fog still relatively mild. I'm really noticing cognitive fatiguability now - I'll get stuck into drafting a letter, concentrate well for 20 minutes, then my brain turn to mush and my typing full of mistakes in every word.
So I'd say I don't have constant brain fog, but it kicks in pretty quickly these days, and I keep having to stop and rest.
If by 'better prognosis' I have no idea for others, but it hasn't been the case for me. I have slowly and steadily got sicker over 30 years.
